Re: Is 350 RWHP Possible ?
 

since you want some track numbers, how about 12.28@108 with ported stock E7s and ported stock "junk" intake. What does that put the HP at?

need we go on?

Re: Is 350 RWHP Possible ?
 

Very impressive,

I seen a car with a pretty much stock motor run a 13.10 @102mph @3000ft here were I am at. He had a little port work done to the exhaust side of his heads, ported lower intake, exhaust and 3.73 gears.

He hurt alot of LS1 owners feelings that night. :cool:

On my car my heads are really too big for a 302 thats why I can do 109mph but at only a 12.50. But thats not bad considering cars run a half second better and 3 or 4 mph more in Dallas or Houston compared to west Texas were I am at.

I am hoping my heads will be a better match with the 331 I have on order. ;)

Re: Is 350 RWHP Possible ?
 

Sounds like it's around the right area, depending on the weight of the vehicle... might have helped to note the intake was professionally ported :rolleyes:

I don't give a flying **** what you think. I've seen far more bullshit on this board than I care to acknowledge; from people claiming to be somebody they're not to cars putting down 350rwhp and trapping 105.

I find it interesting that your combo is listed as GT-40P's with a 4* retarded stock cam, a ported Explorer intake, 1.7 roller rockers, and you managed about 15 crank hp less than the "stock" combo at 277rwhp on the dyno.

unit, The zo6 i was talking about was an 02, not a 7.0 litre like the c6, i saw it run 9.9 @ 143, yea it's modded h/c/100 shot, but on a stock bottom end!..... no nos, low 10's
believe it or not, 'mike murrillo' owns it, In that case im sure the car's ecu is tuned to the max, since he is a well known stang tuner as well.
With that said, A 351/stroker windsor could probaly turn out the same #'s with some high dollar parts?

Re: Is 350 RWHP Possible ?
 

ditto on the first comment, your a class guy I can tell.

interesting that you pull a my **** is bigger than yours type comment on my car. It's a daily driver that I don't race - and the cam is 4 degrees advanced, not retarded. Peak numbers don't mean squat to me - average torque does.

Re: Is 350 RWHP Possible ?
 

Tmoss, The port work you do has got to be good, I actually heard your name mentioned at our local track this past wed from some guy :) I know you post in the corral as well, but im glad to kinda know ya, you celebrity you:D

Re: Is 350 RWHP Possible ?
 

My work has worked out well for many and I've got a little national ink, but that is a far cry from celebrity. Thanks though. I just couldn't stand by and not respond to a flat out statement that something couldn't happen - that I have seen happen numerous times.

Re: Is 350 RWHP Possible ?
 

Just a little more for all to see. 89grocerygetter has got to be my hero. We built his combo on what we could get at the time. 165 AFRs, holly intake, 318 dodge dakota injectors, A mass air meter???, a HR266XE cam (?) (Memory sucks) a stock TB, and a STOCK 100k bottom end, tremac 3550, and 4.10 gears. 11.97 @116mph in a LX with JUST the back seat removed. What does his HP #s come out to be?

Re: Is 350 RWHP Possible ?
 

you need to know what his car weighed.............but it will be close to 375-390HP for the speed and ET. That is smokin for that combo...........

Re: Is 350 RWHP Possible ?
 

I don't think I ever made the case that a 351 stroker couldn't run those kinds of times when heavily modified. Ford's NASCAR engines are a variant of the 351 and they are capable of well over 750hp in non-restrictor plate form. Depending on the track weight of the Corvette, 140mph traps would certainly lead me to believe he's making 600hp at the crank. A little over 500hp from a highly modified N/A Z06 is certainly believable considering they were making over 400 prior to mods! Since it was a production car, you know the engineers spent a lot of time making sure the engine was streetable, allowing the aftermarket to benefit from concepts that already worked, but could still be refined to produce more without tremendous sacrifices. Even if it's not the 7.0L C6 engine, you're still talking about an engine that is using a design that is largely 40 years newer than the 302/351, and the 5.0 is still at a 15% displacement disadvantage assuming the 'Vette is isn't bored out. You indicated it's on the stock bottom end so I'm assuming that it isn't stroked.

The LS1's respond exceptionally to modification from all I've ever seen. The 302 has been out of production for over a decade, and the R&D aftermarket for it is not as aggressive as it once was. The 351W's market was largely based off the 302 since high performance 351Ws hadn't been produced by Ford in well, about 35 years. At 240hp, the Lightning doesn't qualify, and the torquey Cobra R used hipo SVT 302 parts to do the job.

If you need any more proof of what a little factory engineering can do, look no further than the GT-40P heads, and how they were superior to the GT-40 Irons despite not being designed for performance applications. The GT-40P heads were designed to produce good torque and pass emissions in a truck, lol.

Re: Is 350 RWHP Possible ?
 

I pretty much left this topic because I had no desire to get into a who has the prettiest smelling shit contest, but it seems as though you think you've somehow quashed my comments, yet I still don't really see where we've disagreed in theory because in each example you've given, something is different than I've quoted (i.e. ported intakes vs stock intakes).

Telling people that (A) is possible or (B) is possible based on a somewhat misleading claim isn't right. i.e. a professional porting job is not a shitty home port job, and a stock intake is not a professionally ported stock intake. Maybe we've got a communication breakdown in the terminology department.

Regardless, I stand firmly by my comments in this thread, and I feel completely at ease doing so. Taking my comments out of context or bending them to apply to a different scenario isn't fair to me or the people relying on your advice to build their combination with the expectations their (A) combo will be capable of (B) performance. I'm not about to blow sunshine up somebody's ass, and that is worth more to me in the "class act" category than even unintentionally misleading people to make them feel better.

Re: Is 350 RWHP Possible ?
 

And I'll stand by my position. I've worked with over 400 people on about every kind of Ford intake that is in common use. None were dissapointed in the results because I didn't "blow sunshine up somebody's ass" either. The results of my work are well documented and my reputation is in tact. You did throw the BS flag on something I know has been done. Done by professional people? - yes, but not a professional race team or high dollar engine builder. I called you on it simply to point out that 280+HP from ported junk stock parts IS possible and they won't have to break the bank to do it.

Your comfortable and so am I.........so just leave it at that.

Re: Is 350 RWHP Possible ?
 

So then it does boil down to a terminology issue. When I say "stock" I mean stock as it left the factory. When you say "stock" you mean a casting that carries the factory part number. Upon re-reading my post, I can see how it would be easy to confuse what I said because I didn't elaborate on "stock."

There's potentially a big difference between as it left the factory and after modification to the factory part. So would you agree that taking a bone stock 5.0 and simply bringing the heads into the garage and having an amateur going at them with a knurled cutting wheel and a drill (i.e. junk home port job), and throwing on a 60mm T/B is not going to get you 285rwhp?

That's what I'm talking about, and that's why I called BS. Everything about my BS call goes out the window as soon as you starting talking about quality headwork on the E7s, and professionally porting the intake, etc.

Re: Is 350 RWHP Possible ?
 

Yes, we did have a disconnect on terms then. I have not seen true stock parts make over 230-240RWHP when assembled and tuned with detail by someone who knows what their doing (without cheating either). The power levels I spoke of were definately about ported stock parts dome by someone who has a clue - either a pro or an avid enthusiest.

Happy New Year to all in the thread. Also, sorry for being an ass, haha.
